Özet
Objective: The aim of this study is to evaluate the treatment of cerebrospinal fluid (CSF) leaks from cochleostomy after cochlear implantation intraoperatively and postoperatively. Methods: Three hundred seven patients (age ranges 13 months to 18 years) were undergone cochlear implantation and 14 (4.56%) of them had CSF leakage intraoperatively (2 normal, 12 anomalous cochlea). Complete packing of the around electrode in cochleostomy with muscle had performed to control CSF leak intraoperatively for primary surgery in 10 patients. Cerebrospinal fluid leakage was observed in 3 patients after cochlear implantation postoperatively. Revision surgeries for CSF leakage with fat tissue sealing were performed for them also. Fat tissue packing was performed for the last 4 patients in primary surgery. Outcomes of management methods for sealing were evaluated. Results: Sealing the cochleostomy with muscle was performed for 10 patients. Fibrin glue applications were used for excessive leakage for 5 patients with cochlear anomalies and 3 of these patients had CSF leak from cochleostomy postoperatively (Patients I, II, III). Secondary surgeries with fat tissue sealing were performed. But CSF leakage also was occurred in Patient III. Subtotal petrosectomy and obliteration of cavity with fat tissue had been performed for Patient III. Cerebrospinal fluid leakage has not been seen in primary surgeries with fat tissue packing in other 5 patients. Conclusion: Cerebrospinal fluid leakage may occur in cochlear implantation patients with inner ear anomalies postoperatively. Sealing of the cochleostomy with fat tissue is more useful than muscle intraoperatively.
